[0002] With the development of industrialization, injection molds are increasingly used in the industrial field. Before injection molding, the shape and water channel connector at the bottom of the bottle mold base need to be inspected to ensure that the water channel connector is not deformed and the water channel is unobstructed. Currently, the above inspection is usually carried out manually by measuring and manually connecting water pipes to inspect the water channel. The cost of manual inspection is high and the inspection efficiency is low. It lacks competitiveness in the industrial field and is not conducive to large-scale promotion and industrial production.

[0012] The beneficial technical effect of this utility model is as follows: The bottle mold bottom core water channel connector testing fixture includes: a first connecting plate, a second connecting plate, a third connecting plate, a rocker arm, a pin, and a connector. In use, the water channel connector is first inserted into the coaxial first test hole, second test hole, and third test blind hole. Since the inner diameters of the first test hole, second test hole, and third test blind hole match the outer dimensions of the water channel connector, when the water channel connector is not deformed, it can fit perfectly into the first test hole, second test hole, and third test blind hole. At this time, the pin presses the valve core and opens it. Then, external water flows through the connector into the water channel within the third connecting plate and into the third test blind hole. Because the water channel connector... The side wall and the inner wall of the third test blind hole are sealed together. Water in the third test blind hole can only flow into the water connector through the open valve core. At this time, the tester judges whether the water flow from the outlet in the bottom of the bottle mold is smooth to determine whether the water channel inside the bottom of the bottle mold is unobstructed. When the water connector is deformed, it cannot be smoothly inserted into the first test hole, the second test hole, and the third test blind hole. At this time, the tester can judge that the shape of the water connector is deformed. Compared with manual measurement, it has higher detection efficiency. At the same time, the water channel can be detected at the same time as the shape. Compared with manual measurement of shape and water channel measurement, the steps are simpler, so the detection efficiency is high. It has the advantage of high detection efficiency.

[0022] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0023] This specific embodiment details the bottle mold bottom core water channel connector testing fixture described in this application, such as... Figures 1-7As shown, the testing fixture for the water channel connector with bottle mold bottom core includes: a first connecting plate 1, a second connecting plate 2, a third connecting plate 3, a rocker arm 4, a pin 5, and a connector 6. The bottom surface of the first connecting plate 1 is fixed to the top surface of the second connecting plate 2, and the bottom surface of the second connecting plate 2 is fixed to the top surface of the third connecting plate 3. At least one first test hole is formed through the first connecting plate 1. The second connecting plate 2 has the same number of second test holes as the first test holes. The third connecting plate 3 has the same number of third test blind holes as the second test holes. The first test holes, second test holes, and third test blind holes are coaxial. The pin 5 is fixed to the bottom surface of the third test blind hole. The connector 6 is fixed to the side wall of the third connecting plate 3. A water channel for connecting the third test blind hole and the connector 6 is formed inside the third connecting plate 3. The water supply system includes a water supply connector 6 that connects to an external water source. The first end of the swing arm 4 is oscillatingly connected to the top surface of the second connecting plate 2. A limiting groove is provided on the top surface of the second connecting plate 2, allowing the swing arm 4 to swing horizontally within the limiting groove. A water supply connector 8 protrudes from the bottom of the bottle mold base 7. The water supply connector 8 extends vertically into the first test hole, then into the second test hole, and finally into the third test blind hole. The side wall of the water supply connector 8 can tightly adhere to the inner wall of the first test hole, the second test hole, and the test blind hole, respectively. The side wall of the water supply connector 8 can be sealed to the inner wall of the third test blind hole. The top of the pin 5 can press the valve core 9 at the bottom of the water supply connector 8 and open the valve core 9. A connecting groove is provided on the side wall of the water supply connector 8, allowing the side wall of the swing arm 4 to be inserted into the connecting groove. In use, first insert the water connector 8 into the coaxial first test hole, second test hole, and third test blind hole. Since the inner diameter of the first test hole, second test hole, and third test blind hole matches the outer dimensions of the water connector 8, when the water connector 8 is not deformed, it can fit perfectly into the first test hole, second test hole, and third test blind hole. At this time, the pin 5 presses the valve core 9 and opens the valve core 9. Then, the tester moves the rocker arm 4 to lock the rocker arm 4 into the connecting groove to fix the water connector 8. Then, the external water source flows into the water channel in the third connecting plate 3 through the connector 6 and then into the third test blind hole. Due to the side wall of the water connector 8 and the inner wall of the third test blind hole, the water connector 8 fits perfectly into the water channel in the third connecting plate 3. With a sealed connection, water in the third test blind hole can only flow into the water connector 8 through the open valve core 9. The tester can then judge the smoothness of the water flow inside the bottle mold bottom 7 by observing the smoothness of the water flow from the outlet 7. When the water connector 8 is deformed, it cannot smoothly extend into the first, second, and third test blind holes. The tester can then determine that the water connector 8 is deformed. This method has higher detection efficiency than manual measurement. Furthermore, the water flow can be tested simultaneously with the external shape measurement, making the process simpler and more efficient. It offers the advantage of high detection efficiency.

[0024] Optionally in this embodiment, the first connecting plate 1 and the second connecting plate 2 are fixedly connected by a first bolt, and the second connecting plate 2 and the third connecting plate 3 are fixedly connected by a second bolt. A first positioning hole is formed through the first connecting plate 1, a second positioning hole is formed through the second connecting plate 2, and a third connecting hole is formed through the third connecting plate 3. The first, second, and third connecting holes are coaxial, and a connecting pin 10 passes through and is interference-fitted with the first, second, and third connecting holes. The connecting pin 10 serves to position the first connecting plate 1, the second connecting plate 2, and the third connecting plate 3.

[0025] Optionally in this embodiment, a fixing ring groove is provided on the inner wall of the third test blind hole. The outer ring of the sealing ring 11 can be engaged in the fixing ring groove, and the inner ring of the sealing ring 11 can be sealed to the side wall of the water connector 8. The sealing ring 11 can play a sealing role to prevent water from flowing into the second test hole.

[0026] Optionally in this embodiment, a swing pin is provided on the top surface of the second connecting plate 2, and the first end of the swing rod 4 is oscillatingly connected to the swing pin.
